- B.转基因抗虫棉能抵抗棉铃虫.可减少农药使用
- C.导入的目的基因可能与感染转基因生物的病原体基因重组
- D.转基因植物的抗除草剂基因.不会通过花粉传播而进入杂草中
正确答案及解析
正确答案
解析
种植转基因作物(如抗虫棉)应与传统农业(普通棉花)种植区隔离，否则转基因作物中的基因可能扩散到普通作物中．使传统农业种植区的产量受到很大的影响，A项正确。转基因抗虫棉可以有效地用于棉铃虫的防治，从而可减少农药使用，B项正确。导入转基因生物的外源基因有可能与感染转基因生物的某些细菌或病原体杂交，从而重组出对人类或其他生物有害的病原体，C项正确。转基因植物如果与杂草之间不存在生殖隔离，种植转基因作物可能通过花粉扩散而使野生植物获得新基因，从而影响野生植物的遗传多样性，D项错误。

根据以下材料，回答题
If you don′t think a phone is the rightgift for a lover, the smart choice this year is a smart phone.
For people who don′t read instructions
The easiest-to-use phone is the iPhone. It′sthat has pushed it to the No.1 selling position, surpassing the Motorola Razr.The iPhone′s touch screen is easy to operate and it′s also easy to customize (用户化). The iPhone can run allsorts of applications such as those help you to lose weight, identify a song onthe radio, find a restaurant or do many other things.
For the futurist
The T-Mobile G1 is very popular as it is thefirst phone to offer a Google browser, meaning that you′re getting the real webon your phone, but it′s the phone′s potential that qualifies it for the futurist.The exciting applications are interesting, but they don′t always work smoothly.Sometimes it is hard to use the applications it comes with. The system shouldimprove as it becomes more popular, so it holds great promise. With fewrestrictions on the design of applications for the phone,
the G1 could be the first phone toincorporate (整合) some of the coolest.
For the road warrior
The new BlackBerry Storm is something likethe equivalent (等同物) of a mullet--a business up front, party in the back. It stillincorporates the serious mail and organization features that have endeared (使受钟爱) these phones to business people. The 3.25-inch is bright anddetailed and it′s a decent size for watching videos on the go.
For the Luddite (反对技术进步的人)
For those who can′t handle buttons and newfeatures, there is the Samsung Jitterbug Dial. Some people are Luddites whojust want a few large buttons to make calls. That′s it, just calls. That makesit even easier to use an iPhone.
